Italian premier Silvio Berlusconi was facing embarrassing new sex allegations yesterday on the eve of a confidence vote that is crucial for the survival of his government.

Maria Teresa ‘Terry’ De Nicolo who worked for an escort agency, said she had shared a bed with the media mogul (73) and two other girls during one of the notorious “festini” or adult parties at his Rome residence in September 2008.

Her statement to public prosecutors investigating corruption claims was leaked to La Repubblica newspaper.

She said there were 15 girls at the party and when she left the next morning Mr Berlusconi gave her jewellery.

Ms De Nicolo (38) said she received £830 to attend the party from Gianpaolo Tarantini, a businessman under investigation for alleged corruption.
